SPECIFICATION formingpart of Letters Patent No. 245.078, dated August 2,1881,

Application filed April 19, 1880. (No model.)

tion of the invention, such as will enable others skilled in the art towhich it pertains to make and use it, reference being bad to theaccompanying drawings, which form part of this specification. I

My invention relates to chimney-caps, its

object being to provide a cap of such construction that all indraftswill be avoided and the smoke freelyconducted to the outer air.

The inventionconsists in the combinations of parts hereinafterdescribed.

In the drawings, Figure l is a vertical section of a chimney-capconstructed in accordance with my invention, and Fig. 2 is a horizontalsection on the line 3 y of Fig. '1. y

A represents a hollow cylindrical chamber or stand provided withcone-shaped ends .0, the upper end being closed and the lower one openand securely connected with a smoke flue or pipe, I. The chamber A isprovided at each of its sides with slots B, forming exits for the smoke.These slots are provided with covers or shields D provided with ends E,the latter being secured to the chamber, thusforming smoke-passages Fbetween the chamber A and the shield D. The sides of these shields areopen to form an exit, G, for the smoke-currents.

It will be seen that the smoke-flue I is of a much less diameter thanthe cone 0, and thus the downward draft incident to chimney-tops wherethe flue and the top are of about an equal diameter is avoided.

The shields D, as shown, are attached some distance above and below theslots B, and owing to their arrangement-one on each side of the chamberA-currents of air are prevented from entering said chamber; but theair-currents, when they strike the top, will pass through two of thespaces F, and by reason of the velocity of such currents the smokeaccumulated in the chamber A will be more readily drawn out, and allindraft is avoided.

It will be apparent that my improvement is not only applicable toordinary chimneys, but may also be applied to the smoke-stacks oflocomotives or steamboats.

I claim--- The combination, with the fiuc I, of the chamber A, havingends (J, smoke-exits B, and

shields D, substantially as set forth.

- In testimony that I claim the foregoing I have hereunto set my handthis 6th day of March, 1880.
